The Quick Read: A second home or mountain cabin can carry a home equity line, but it is a narrower corner of the product, and which lenders fit depends on how the cabin is used, how it is titled, and how much equity sits in it.
- On a second-home line, the ceiling reaches 90% combined loan-to-value (CLTV), and only at a 720 or better credit profile. A 640 profile supports 75% CLTV.
- On an investment-property line, the ceiling is 70% CLTV with a 700 minimum credit profile.
- Second-home and investment lines are capped at $500,000, and only an individual or a revocable living trust can hold title.
- Rental use can reclassify the cabin. Log homes and manufactured homes are not eligible.
Lendmire is a mortgage broker, not a lender. It places these lines through a network of wholesale lenders and matches the file to the program that fits. Every figure here is subject to lender guidelines and full file review, and none of it is a commitment to lend.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
What a HELOC on a Cabin Actually Is
A home equity line of credit (HELOC) is a revolving credit line secured by property you own. You borrow against equity, repay, and borrow again within a set window.
On a second home, the cabin itself is usually the collateral. Each lender behind these programs sets its own limits, so terms vary from one to the next.
These programs are standalone lines, placed in first or second lien position. Lendmire’s HELOC placements run through select wholesale partners in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than Lendmire’s 41-market DSCR footprint, which includes Washington, D.C. Check the property’s state first.
Which lenders fit depends on the property type, credit profile, leverage need, and how you document income. A broker that shops several wholesale lenders can screen for those things before you apply.
Key Terms Defined
HELOC: A revolving line secured by real estate, with a draw period followed by repayment.
CLTV (combined loan-to-value): Your first mortgage plus the full new line, divided by the property’s value.
Occupancy classification: The lender’s label for the property: primary home, second home, or investment property. Everything else follows from it.
Draw period: The stretch when you can borrow and pay interest only. After it ends, you repay principal and interest over a fixed remaining term.
Vesting: How title to the property is held, such as an individual, a revocable trust, or an LLC.
DSCR cash-out refinance: A new investor loan, qualified primarily on property-level rental income covering the payment, subject to lender guidelines. It replaces the existing mortgage and returns equity as cash.
How Underwriting Treats a Cabin, Step by Step
Underwriting runs in a set order. Knowing the order shows you where a file stalls.
1. The lender classifies occupancy. A second home is a property you use yourself. Rental income on a tax return, regular bookings, or a management agreement can push the cabin into investment-property treatment. That label changes the ceiling and the credit floor.
2. The lender values the property. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and you may request a full appraisal on any line.
A remote cabin deserves a thought here. Automated models lean on nearby sales, and rural mountain areas can have few of them. If the cabin sits on a long gravel road with thin comparable sales, asking for a full appraisal may be worth it.
3. The lender calculates CLTV. Add the first mortgage and the full new line, then divide by value. Say the first mortgage equals 50% of value and the new line equals 25%. That is 75% CLTV, which a 640 second-home profile supports. A 660 profile is what reaches 80% CLTV on a second-home line.
4. The lender tests credit and debt-to-income. Second homes carry a 640 minimum credit profile. The score comes from a single-bureau model keyed to the primary wage earner, and the report can be no more than 90 days old at closing.
Debt-to-income (DTI) tops out at 50%. The 45% limit for profiles from 600 to 679 applies to primary residences only, since a second home starts at 640. On a second home, any ratio above 45% requires at least a 680 profile. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow. Your primary mortgage, the cabin mortgage, and the new line all count.
5. The lender checks title and property type. This step catches more files than many borrowers expect. Both topics get their own sections below.
6. The line funds, and the rules keep running. At least 75% of the line is drawn at closing. Draws after closing carry a minimum as well. The longer-runway program states it as $1,000 (Texas is $4,000), while the higher-leverage program does not state a subsequent-draw minimum. The last section before the FAQ covers what can happen to an open line.
Ceilings by Occupancy
The ceiling depends on how the cabin is classified. Here is how the network’s HELOC tiers look side by side:
| Occupancy | Credit profile | Max CLTV | Line cap |
|---|---|---|---|
| Second home | 640+ | 75% | $500,000 |
| Second home | 660+ | 80% | $500,000 |
| Second home | 680+ | 85% | $500,000 |
| Second home | 720+ | 90% | $500,000 |
| Investment property | 700+ | 70% | $500,000 |
Read the table by occupancy first. The 90% second-home ceiling exists only at 720 and above. The investment-property ceiling stays at 70% CLTV with no higher tier.
If you are browsing lender pages, remember that other sources report different CLTV figures for equity lines. Those describe the broader market, and a given lender’s own cap may sit above or below them. Use the network figures above for these programs.
A larger equity cushion helps, but it does not erase a credit floor or a property-type exclusion. A strong file clears both: enough equity and an eligible property.
Draw and Repayment Structures
Two draw structures exist on primary residences and second homes:
- A 3-year interest-only draw followed by a 17-year fully amortizing repayment.
- A 5-year interest-only draw followed by a 25-year fully amortizing repayment.
Tennessee shortens both, to 3 years with 12 years of repayment and 5 years with 10 years of repayment. Investment lines run the 5-year draw and 25-year repayment structure only, and in Tennessee that structure is shortened to the 5-year draw with 10 years of repayment.
Pricing on these lines floats across both the draw and the repayment period, and it does not convert to fixed. If you want a fixed term on the cabin, that points toward a fixed-term refinance instead.
Interest-only is not a free pass. When the draw ends, principal repayment begins, and the required payment steps up.
Cabin-Specific Property Issues
A mountain cabin runs into property-type rules that a suburban house never meets.
Eligible: single-family homes, 2-4 unit properties (640 minimum on one program), PUDs, townhomes, and condominiums, including non-warrantable condos. Modular factory-built homes are eligible on one program only.
Not eligible on either program: manufactured homes, co-ops, condotels, log homes, commercial or mixed-use properties, and anything with agricultural zoning.
The log-home exclusion matters most here. A true log cabin falls outside these programs, however well it is kept up. The same goes for a cabin on a parcel zoned for agriculture. In DSCR lending, the network does not offer manufactured homes, log homes, or barndominiums either.
Several states add rules for cabin buyers. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA. Texas properties are limited to 10 acres. New Mexico and Ohio apply a CLTV cap that depends on the credit profile.
Title: Who Can Hold the Cabin
The line goes to an individual or an inter vivos revocable living trust, on fee simple or leasehold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.
This is the sharpest structural difference from a DSCR loan. Many cabin owners put the property in an LLC for liability reasons. If yours is already deeded to one, you need a vesting change or a DSCR cash-out instead of a HELOC, subject to lender program eligibility.
Exposure limits matter for owners with several properties. A borrower can hold at most three lines, and an owner with more than 15 financed properties is not eligible.
Where the General Rule Breaks
Rental use. Weekend bookings, a rental pool, or a management agreement that controls occupancy can turn a second home into an investment property. Then the 70% CLTV ceiling and 700 credit minimum apply instead of the second-home tiers. Declare the use honestly at application. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Line size. Size limits matter most to owners who also borrow against a primary home. A primary-home line above $500,000 caps at 75% CLTV and requires a full appraisal.
Sub-640 credit. A sub-640 profile is limited to single-family residences with a clean 12-month housing history. Because second homes floor at 640 and investment at 700, that carve-out reaches primary residences only.
Derogatory history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program. One program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other declines the history regardless of age.
Self-employed owners. Income can be documented under the applicable program, subject to lender guidelines. Lendmire’s piece Top Bank Statement HELOC Providers on a Second Home or Mountain Cabin covers that path.
Using a Primary-Home Line to Buy the Cabin
A HELOC lender looks at the collateral, not at what the money buys. A line secured by your primary home can fund a cabin down payment. Some borrowers prefer that path because the cabin’s occupancy classification never comes up.
The tradeoff is risk. Your primary home secures the debt, so a cabin purchase that goes badly puts your main residence behind the loan. A line secured by the cabin puts the cabin at risk instead.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
The Risk After Closing: Freezes and Cuts
An approved line is not a guaranteed pot of cash. The CFPB’s HELOC brochure says lenders can generally freeze or reduce a line if the home’s value falls or your finances worsen. The CFPB’s plain-English HELOC answer says a significant value decline or changed finances can restrict draws.
Lenders must reinstate privileges once the conditions behind a freeze no longer exist. That helps, but you may still be without access when you need it.
The practical lesson: if you plan to draw later, such as for a renovation season or a down payment on a rental, do not treat the unused line as certain liquidity.
When a DSCR Cash-Out Fits Better
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
If the cabin is a true rental, a DSCR cash-out refinance may fit better than a HELOC. The DSCR cash-out tops out around 75% LTV on standard rentals and around 70% on short-term-rental collateral. About 6 months of ownership seasoning is the common expectation. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and the network generally holds to 30-year fixed structures above $2,500,000.
The DSCR compares monthly rent to the full monthly obligation: principal, interest, taxes, insurance, and any HOA dues. A ratio of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the ratio.
A cabin owned by an LLC can use this route, subject to lender program eligibility. The 30-year fixed is the spine of these programs, with 40-year terms and interest-only periods available through select lenders. Reserves vary by lender, leverage, loan size, and transaction type, commonly around 6 months of principal, interest, taxes, insurance, and dues. The loan structure itself is different, so see the complete DSCR loans guide for the full picture.
Questions to Ask Before You Apply
Screening questions save time before any application:
- How will the lender classify the cabin, given how you use it?
- What CLTV tier does your credit profile reach on a second-home line?
- Will the property type, zoning, and state clear the eligibility rules?
- Can the lender hold title the way you hold it, or does an LLC force a different loan?
- Does the lender order an automated valuation, and can you request a full appraisal?
- Is your DTI under 50%, counting the primary mortgage, cabin mortgage, and the new line at maximum draw?
Frequently Asked Questions
Can I get a HELOC on a cabin I rent out some of the year?
It depends on how much you rent. Regular bookings or a management agreement can reclassify the cabin as an investment property. That moves the line to a 70% CLTV ceiling and a 700 minimum credit profile.
Does a cabin line need a full appraisal?
Not always. Lines at or below $500,000 ordinarily run an automated valuation, though a higher CLTV may require a secondary valuation. A cabin with few nearby comparable sales may be a reason to request a full appraisal yourself.
Can an LLC hold title on the cabin?
No. Only an individual or a revocable living trust can hold title for these lines. A cabin already in an LLC points to a vesting change or a DSCR cash-out instead.
Can I use my primary home to buy the cabin?
Often, yes. A line secured by your primary home can fund the cabin purchase, and the cabin’s occupancy classification does not come up. Your primary home becomes the collateral, though, so weigh that risk.
Is a log cabin eligible?
Not through these programs. Log homes, manufactured homes, and agriculturally zoned properties fall outside them.
